all opalina modules ship with the opx filter input expander.
stereo state-variable filter networks configurable in two modes. resonator is a triple bandpass alignment, emphasizing resonant peaks and formants. isolator is a cascaded state-variable topology with variable mid-bandwidth for use as resonant crossover.
features:
resonator: triple bandpass filters with vc peak span and resonance. 12db/oct filter slopes.
isolator: cascaded state-variable filters with vc bandwidth and resonance. 24db/oct filter slopes.
completely analog signal path.
individual band inputs and outputs.
continuously variable band input amplitude.
soft-clipping circuit on sum output.
dual channel for use in stereo (l & r).
specifications:
width: 14hp
depth: 35mm
power consumption: +12v 95ma /-12v 95ma
